Oh, I thought C23 used '_', since Python uses that. I prefer single 
quote as that is not shifted on my keyboard. (My language projects just 
allow both!)

That fact that it is not widespread is a problem however, so I can't use 
either without restricting the compilers that can be used.

For example gcc 14.x on Windows accepts it with -std=c23 only; gcc on 
WSL doesn't; tcc doesn't.
